+* Freescale MXS GPIO controller
+
+The Freescale MXS GPIO controller is part of MXS PIN controller. The
+GPIOs are organized in port/bank. Each port consists of 32 GPIOs.
+
+As the GPIO controller is embedded in the PIN controller and all the
+GPIO ports share the same IO space with PIN controller, the GPIO node
+will be represented as sub-nodes of MXS pinctrl node.
+
+Required properties for GPIO node:
+- compatible : Should be "fsl,<soc>-gpio". The supported SoCs include
+ imx23 and imx28.
+- interrupts : Should be the port interrupt shared by all 32 pins.
+- gpio-controller : Marks the device node as a gpio controller.
+- #gpio-cells : Should be two. The first cell is the pin number and
+ the second cell is used to specify optional parameters (currently
+ unused).
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells : Should be 2. The first cell is the GPIO number.
+ The second cell bits[3:0] is used to specify trigger type and level flags:
+ 1 = low-to-high edge triggered.
+ 2 = high-to-low edge triggered.
+ 4 = active high level-sensitive.
+ 8 = active low level-sensitive.
+
+Note: Each GPIO port should have an alias correctly numbered in "aliases"
+node.
+
+Examples:
+
+aliases {
+ gpio0 = &gpio0;
+ gpio1 = &gpio1;
+ gpio2 = &gpio2;
+ gpio3 = &gpio3;
+ gpio4 = &gpio4;
